Our Expanding Universe: Delving Into Dark Energy

The universe is stretching out ever more rapidly - a phenomena known as cosmic acceleration - and scientists don't know why. Understanding the "dark energy" that is causing this expansion would help them put together a clearer picture of the universe's history. Scientists supported by the Department of Energy's Office of Science are using massive telescopes to chart how dark energy has influenced the structure of the universe over time.
